Fix Sinking Herman Miller Aeron Chair

You sit down on your Herman Miller Aeron chair but it immediately sinks on its own. Sometimes it will even sink slowly as you do your work. Luckily, there is a simple one time fix for this issue. Simply, pop open the cover of the Aeron chair controls under the seat. You will see a screw sitting on top of the chair’s cylinder. Loosen that screw just a bit. That is it, your Aeron is now fixed. You can watch the following video to see how easily your Aeron could be fixed.

Please note: Do not overtighten the screw because the chair will go up and down on its own. Please see the following photos for correct position of the screw.
